Description

Technical Field

[0001] The invention relates to the technical field of metal pipe bending equipment, and in particular to a bending device for producing electric iron accessories. Background Art

[0002] Power iron accessories are an important component of power transmission and distribution systems for supporting, fixing, connecting and protecting power lines and equipment. In order to meet the specific geometric requirements of structural parts in power engineering and ensure that power accessories can be correctly aligned, connected and bear the expected mechanical and electrical loads at the installation site, some tubular power accessories need to be bent. If the tubular power accessories are bent directly, deformation and wrinkles are likely to occur at the bends of the pipes, affecting the bending quality of the tubular power accessories.

[0003] The patent document with authorization announcement number CN113399517B discloses an anti-wrinkle processing method for aluminum alloy bent pipe fittings. First, the pipe fittings are positioned and installed, and then an inner liner tube with an outer diameter the same as the inner diameter of the pipe fitting to be bent is inserted into the pipe fitting. The end of the inner liner tube passes through the position to be bent, and the pipe fitting is bent by a bending machine until a preset bending angle is reached. The bending machine includes a workbench and a clamping device and a bending device arranged on the workbench. After the pipe fitting is bent, the bent part of the pipe fitting is cut off by a cutting device. The pipe bending method provided by the patent document inserts an inner liner tube into the pipe fitting, so that the inner wall of the pipe fitting is not easily irregularly deformed under the support of the inner liner tube, thereby reducing the generation of wrinkles at the bend.

[0004] In order to adapt to the bending of pipe fittings, the liner tube provided in the above patent document is made of rubber material. When the pipe fitting is bent, one end of the liner tube directly passes through the end of the pipe fitting, and the other end is fixed on the winding roller. During the bending and cutting process, the liner tube can be wound and released by controlling the operation of the tube winding motor. The anti-wrinkle processing method for pipe fittings provided in the patent document can effectively reduce the wrinkles generated during the bending operation of the pipe fittings. However, the use of rubber liner tubes to support the pipe fittings requires replacing liner tubes of corresponding sizes according to pipe fittings of different diameters. In addition, in order to ensure the anti-wrinkle effect when the pipe fittings are bent, the liner tube needs to fit the inner wall of the pipe fitting to support the pipe fitting. When the pipe fitting needs to be bent to a large extent, such as when the pipe fitting is processed into a U-shaped bend, because the bending angle of the pipe fitting is large and the rubber liner tube fits closely to the inner wall of the pipe fitting, it will be difficult for the liner tube to separate from the pipe fitting. Summary of the invention

[0005] The present invention provides a bending device for producing electric iron accessories, aiming to solve the problem in the related art that when tubular electric accessories are bent, the inner liner pipe serving as an auxiliary support cannot adapt to pipe fittings of different diameters and the inner liner pipe is difficult to remove after the pipe fitting is bent at a large angle.

DETAILED DESCRIPTION

[0036] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0037] like Figure 1 As shown, the bending device for producing electric iron accessories of the present invention comprises a workbench 1, on which a clamping mechanism 11, a bending mechanism 12 and a supporting mechanism are provided. The clamping mechanism 11 is used to clamp and fix the pipe 4 to be bent, and ensure that the pipe 4 does not slide or rotate during the bending process. The clamping mechanism 11 is detachably connected to the pipe 4, one end of the supporting mechanism is connected to the clamping mechanism 11, and the supporting mechanism can also be provided with a detachable connection structure with the clamping mechanism 11, so as to facilitate the daily maintenance and Maintenance, the bending mechanism 12 is used to apply a bending force to the pipe fitting 4 so that the pipe fitting 4 is bent to a specified bending angle. When the pipe fitting 4 is bent, the pipe fitting 4 is first fixed to the clamping mechanism 11, and the supporting mechanism is kept extending into the pipe fitting 4. The supporting mechanism is coaxially arranged with the pipe fitting 4. The bending mechanism 12 bends the pipe fitting 4 to a specified angle at a specified position of the pipe fitting 4. During the bending process of the pipe fitting 4, the supporting mechanism supports the pipe fitting 4 inside the pipe fitting 4 to reduce wrinkles and deformation problems at the bending point of the pipe fitting 4.

[0038] like Figure 2 and Figure 3As shown, the support mechanism includes multiple groups of support components and multiple connecting members 3, any two adjacent support components are connected by the connecting members 3, and the connecting members 3 are rotatably matched with the support components, with the side facing the clamping mechanism 11 as the front side, the front end of the connecting member 3 is provided with an adjusting portion 31, and the rear end of the connecting member 3 is provided with a resetting portion 32, the support assembly includes a base 2, a support member 21, an adjusting structure and a resetting member 26, the base 2 is oblong, the adjusting portion 31 is rotatably matched with the front end of the base 2, the resetting portion 32 is rotatably matched with the rear end of the base 2, there are two support members 21, the two support members 21 are slidably matched with respect to the base 2, and the adjusting structure cooperates with the adjusting portion 31 to push the two support members 21 relatively away from each other until the support members 21 are in contact with the inner wall of the pipe 4. The support members 21 on each support assembly extend as the position of the force point on the pipe 4 changes during the bending process of the pipe 4. The bending mechanism 12 includes a bending mold and a driving system. When the bending mechanism 12 performs a bending process on the pipe 4, the driving system pushes the bending mold to apply a bending force to the pipe 4, so that the pipe 4 bends along the contour of the bending mold, that is, the force position of the pipe 4 changes during the bending process of the pipe 4. During the bending process of the pipe 4, each group of support assemblies on the support mechanism sequentially extends the support members 21 as the force position of the pipe 4 changes, that is, the extended position of the support members 21 corresponds to the bending force point of the pipe 4, so as to ensure that the pipe 4 is fully supported during the bending operation of the pipe 4 and reduce the generation of wrinkles and deformation during the bending process of the pipe 4.

[0039] like Figures 4 to 7 As shown, the adjustment structure includes an adjustment gear 23, an adjustment rack 24 and an adjustment member 22. The adjustment gear 23 is rotatably matched with the base 2. There are two adjustment racks 24. The two adjustment racks 24 are respectively connected to the two support members 21, and the tooth surface ends of the two adjustment racks 24 are opposite. The length direction of the adjustment racks 24 is parallel to the moving direction of the support member 21. The two adjustment racks 24 are meshed with the adjustment gear 23 at the same time. The adjustment member 22 is slidably matched with the front support member 21 along a direction perpendicular to the length of the adjustment racks 24, and the adjustment member 22 is on the support member 21. It is fixed relative to the support member 21 in the direction of movement, and the adjusting portion 31 is movably abutted against the adjusting portion 22. When the pipe 4 is bent, the supporting mechanism bends with the pipe 4 inside the pipe 4, and the adjusting portion 31 of the connecting member 3 rotates relative to the base 2 and pushes the adjusting portion 22 to slide. The adjusting portion 31 further slides with the supporting member 21 connected thereto. When one supporting member 21 slides, the meshing transmission action of the adjusting gear 23 and the adjusting rack 24 drives the other supporting member 21 to move in the opposite direction. Finally, the two supporting members 21 are relatively far away from each other and support the pipe 4 by adhering to the inner wall of the pipe 4.

[0040] The support member 21 includes a connecting portion 211 and a supporting portion 212. The adjusting rack 24 is fixed to the connecting portion 211. The connecting portion 211 is slidably matched with the base 2. In order to limit the sliding direction of the support member 21, the connecting portion 211 is connected to the base 2 through a telescopic rod 25. The length direction of the telescopic rod 25 is the extension direction of the support member 21. The supporting portion 212 is located on the outside of the base 2, with the side of the supporting portion 212 opposite to the inner wall of the pipe 4 as its outside. In order to improve the fitting effect of the supporting portion 212 with the inner wall of the pipe 4 when supporting the pipe 4, the outer side of the supporting portion 212 is in an arc shape, and the supporting portion 212 is preferably made of elastic material. The material of the supporting portion 212 includes but is not limited to rubber.

[0041] The adjusting member 22 is provided with a movable portion 221, and the movable portion 221 slides with the supporting member 21 in a direction perpendicular to the length of the supporting member 21. The adjusting member 31 is provided with a paddle 311, and the paddle 311 is connected to the adjusting member 31 through a torsion spring, and the paddle 311 rotates unidirectionally relative to the adjusting member 31, that is, the paddle 311 can only push the adjusting member 22 to extend the supporting member 21. When the adjusting member 31 rotates in the reverse direction, the paddle 311 rotates relative to the adjusting member 31 and passes over the movable portion 221 without pushing the adjusting member 22 to move in the reverse direction. In order to avoid interference between the paddle 311 and the connecting portion 211 when pushing the movable portion 221 to move, the paddle 311 is configured as an elastic and retractable structure.

[0042] The reset member 26 is used to reset the support member 21 after the force point on the pipe 4 moves, so that the pipe 4 can be smoothly separated from the support mechanism after the bending process of the pipe 4 is completed, reducing the resistance of the support mechanism when the pipe 4 is taken out. The reset member 26 is rotatably matched with the base 2, and the reset portion 32 pushes the reset member 26 to rotate when it rotates relative to the base 2. The reset portion 32 and the reset member 26 are rotated and transmitted. Specifically, a tooth portion is provided on the peripheral side of the reset portion 32, and the reset member 26 is cam-shaped. The peripheral side of the reset portion 32 is provided with a tooth portion, and the teeth of the reset portion 32 are meshed with the teeth of the reset member 26, so that when the reset portion 32 rotates, the reset member 26 is driven to rotate under the meshing action of the teeth, and the reset member 26 is away from the reset portion A push rod 27 is provided at one end of 32, and the push rod 27 extends between the adjusting member 22 and the connecting portion 211. When the reset member 26 rotates, the push rod 27 pushes the adjusting member 22 away from the connecting portion 211. The adjusting member 22 is connected to the support member 21 through a spring so that the adjusting member 22 is reset after the adjusting member 22 is not acted upon by the thrust of the push rod 27. The telescopic rod 25 connecting the base 2 and the connecting portion 211 is an elastic telescopic rod 25. When the support member 21 extends relative to the base 2, the telescopic rod 25 is stretched and stores force. When the push rod 27 pushes the adjusting member 22 to move relative to the connecting member 3, the movable portion 221 on the adjusting member 22 is disengaged from the adjusting portion 31, and the support member 21 is reset under the elastic force of the telescopic rod 25, and drives the other support member 21 to reset through the adjusting gear 23.

[0043] The specific working mode of the bending device provided in this embodiment is as follows:

[0044] In the initial state, the supporting components of the supporting mechanism are located on the same straight line. First, the pipe 4 to be bent is sleeved on the supporting mechanism, and the end of the pipe 4 is fixed to the clamping mechanism 11. The position of the clamping mechanism 11 is moved to the bending mechanism 12 and the position of the pipe 4 to be bent. The bending mechanism 12 pushes the bending die to apply a bending force to the pipe 4 through the driving system. The supporting components in the supporting mechanism that are opposite to the bending position of the pipe 4 are relatively deflected. When two adjacent supporting components are deflected from the horizontal state to the bent state, the adjusting portion 31 rotates relative to the base 2. In this process, the rotation direction of the adjusting portion 31 is positive rotation. The opposite direction is the reverse rotation direction of the adjusting part 31. When the adjusting part 31 rotates forward, the adjusting member 22 is pushed to move toward the outside of the base 2 through the paddle 311. The adjusting member 22 pushes the two supporting members 21 to extend and fit with the inner wall of the tube 4 at the stress-bearing position. The telescopic rod 25 connecting the supporting members 21 is stretched and in a force storage state. The bending mold fits with the outer wall of the tube 4 at the stress-bearing position, ensuring the supporting effect of the supporting mechanism on the tube 4 during the bending process of the tube 4. The supporting part 212 of the supporting member 21 fits with the inner wall of the tube 4 for support, which can effectively reduce the generation of wrinkles and deformation at the bending position of the tube 4 during the bending process.

[0045] The first support assembly that deflects is the first support assembly, and the support assembly located at the rear side thereof is the second support assembly. As the bending operation proceeds, the force point of the pipe 4 continues to move backward, and the second support assembly deflects relative to the first support assembly as the pipe 4 is bent. The connecting member 3 at the rear side of the first support assembly rotates relative to the first support assembly, and pushes the reset member 26 to rotate through the reset portion 32. When the reset member 26 rotates, it further pushes the adjustment member 22 away from the paddle 311 on the adjustment portion 31 through the push rod 27 until it is completely disengaged from the paddle 311. The telescopic rod 25 in the force storage state pulls the support member 21 to reset, so that the support member 21 of the first support assembly releases the support for the inner wall of the pipe 4, and the second support assembly repeats the supporting action of the first support assembly to the new force position on the pipe 4. Support, each support assembly located on the rear side of the second support assembly also supports and resets the pipe fittings 4 one by one as the force position on the pipe fitting 4 changes. The support assembly resets in time after completing the support of the force position of the pipe fitting 4. After the bending process of the pipe fitting 4 is completed, only the support member 21 on the last support assembly is in an extended state, and the resistance it produces on the pipe fitting 4 is relatively small, which greatly reduces the difficulty of separating the pipe fitting 4 from the support mechanism, making it easy to remove the pipe fitting 4 smoothly after the pipe fitting 4 is bent, and the support mechanism can adapt to pipe fittings 4 of different diameters within a certain range, thereby improving the versatility of the support mechanism. In addition, timely resetting of the support assembly after the bending force position changes can also effectively reduce the possibility of the support assembly squeezing and deforming the pipe fitting 4 from the inside of the pipe fitting 4, thereby improving the quality of the bending process of the pipe fitting 4.

[0046] The bending device provided by the present invention can provide bending support and protection for pipes of different diameters within a certain range, reduce the generation of wrinkles and deformation during the bending operation of the pipes, and reduce the difficulty of separating the pipes from the support mechanism after the pipes are processed.
